The present cross-sectional study used the 6-minute walk test (6MWT) to compare the physical proficiency of children and adolescents who had a diagnosis of MB with that of children and adolescents who demonstrated nasal breathing (NB). A total of 80 patients aged 7 to 15 years were divided equally (n = 40) into MB and NB groups and underwent 2 6MWTs at 15-minute intervals. Cardiorespiratory variables--heart rate, respiratory rate, and peripheral oxygen saturation--were analyzed at 3 observation periods (OPs): OP₀, baseline; OP₁, after the first 6MWT; and OP₂, after the second 6MWT. In addition, the distance traveled and the modified Borg scale (MBS) score, which measures perceived exertion, were recorded at OP₁ and OP₂. Statistical analyses included repeated-measures analysis of variance and t tests for continuous variables and the chi-square test for categorical variables, and the significance level was set at P < 0.05. Statistically significant increases in heart and respiratory rates from OP₀ to OP₂ were observed among both male and female patients in the MB group. Peripheral oxygen saturation showed a statistically significant increase from OP₀ to OP₂ among male patients in the MB group. Male patients in the MB group also showed significant increases in MBS scores from OP₀ to OP₁ and from OP₀ to OP₂. In female patients in the MB group, MBS scores increased significantly only from OP₀ to OP₂. Intergroup comparisons of mean values revealed statistically significant differences between male MB and NB patients for both the total distance covered and for MBS scores at both OP₁ and OP₂, with patients in the MB group traveling a shorter distance and reporting greater exertion. The present study established the utility of the 6MWT for assessment of physical proficiency in children and adolescents with varied breathing patterns. The results indicated that MB had a significant negative impact on physical proficiency in male children and adolescents. Female patients with a diagnosis of MB showed a clinical reduction in measures of physical proficiency, but the differences were not statistically significant.</p>","PeriodicalId":12571,"journal":{"name":"General dentistry","volume":"73 1","pages":"68-76"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143624233","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At a follow-up visit 2.5 years later, the permanent mandibular left central incisor (tooth 24) was erupting and presented a change in color along with a reduction in the enamel thickness. A temporary restoration of the hypoplastic defect was performed when the child was 7.7 years of age. This conservative approach was chosen based on the child's behavior and because the lesion boundary was located near the free gingival margin due to the eruption stage of the tooth. The procedure was carried out without local anesthetic, utilizing a resin-modified glass ionomer cement and cotton roll isolation. This patient-friendly approach allowed simplification of the steps involved in the process. The child and his guardian were satisfied with the temporary restoration, and the boy regained his self-reliance regarding dental care.

The W-index is based on oblique line contrast on panoramic radiographs, in which the pixel intensity of the oblique line is compared with the pixel intensity of adjacent structures at the mandibular ramus. A total of 333 patients with panoramic radiographs and pDXA results were evaluated according to T-score results and WI measurements. A Spearman correlation test was executed to assess the correlation between measures. Patients were divided into 3 groups: normal bone mineral density (BMD), osteopenia, or osteoporosis. The WI values were compared with the Kruskal-Wallis test. A significant but negligible correlation was found between the pDXA and WI results for all peripheral sites assessed. Statistically significant differences in the WI results emerged between patients with normal BMD and osteoporosis (P = 0.007) as well as between those with osteopenia and osteoporosis (P = 0.010). There were no significant differences in WI between patients with normal BMD and osteopenia (P = 0.598).

A 74-year-old man presented with a 6 × 6-cm expansile, ulcerated mass on the right lateral palate. A clinical diagnosis of squamous cell carcinoma was rendered. A biopsy was performed, and the specimen showed multiple histologic patterns of ameloblastoma inconclusive of odontogenic or sinonasal origin. Cone beam computed tomographic imaging demonstrated a well-defined unilocular mass in the right maxilla extending up to the nasal cavity. A surgical resection was performed and confirmed the diagnosis of maxillary ameloblastoma with extension into the nasal cavity. This dilemma in delayed diagnosis led to a literature search for similar maxillary ameloblastoma cases with extension into vital structures. In 45 cases previously reported in the literature, the median age of patients with maxillary ameloblastoma was 50 years, and there was extensive involvement of adjacent vital structures. The nasal cavity/sinonasal region (24/45), orbit/orbital floor (12/45), multiple fossae (5/45), and base of the skull (4/45) were the most common extensions of maxillary ameloblastoma. Fifteen patients had lesions with multiple extensions, and 1 patient showed lung metastasis. The most common histologic presentation was the follicular pattern, followed by the plexiform pattern or mixed follicular and plexiform patterns. Surgical interventions were performed on most patients, with the majority undergoing maxillectomy. Differentiating primary sinonasal ameloblastoma from gnathic ameloblastoma with sinonasal extension is challenging, and this article discusses subtle radiographic criteria and symptoms that aid in the distinction of both types. The authors suggest that variants of maxillary ameloblastoma with extensive involvement of the sinonasal region, orbit, or base of the skull be classified with a clinical diagnosis of maxillofacial ameloblastoma, regardless of the tumor origin.</p>","PeriodicalId":12571,"journal":{"name":"General dentistry","volume":"72 6","pages":"54-61"},"PeriodicalIF":0.0,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142498619","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The implant, in the region of the first molar, was osseointegrated and showed radiographic bone loss associated with a probing depth of 8 mm and bleeding on probing. The diagnosis was peri-implantitis, and a surgical treatment approach was selected to enable decontamination of the area with a combination of mechanical debridement, tetracycline hydrochloride (500 mg/mL), and photodynamic therapy. After the decontamination process, a sodium bicarbonate spray device was used, and a guided bone regeneration protocol with a xenogeneic graft and collagen membrane was performed to reestablish the peri-implant bone height. A connective tissue graft was placed to obtain a better biological seal and increase the peri-implant keratinized mucosa. Follow-up examinations performed 30 days, 5 months, 3 years, and 6 years after the surgical procedure revealed new bone formation and progressively reduced probing depths.
